  1. 1. ASSESSING MICROBIAL COMMUNITY RESPONSES IN A CHEMICALLY STRESSED FRESHWATER ECOSYSTEM USING ENVIRONMENTAL DNA

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Nicolai Laufer; [2023-06-21]
    Nyckelord :;

    Sammanfattning : Microbial communities represent the fundamental cornerstones of riverine ecosystems because they are involved in numerous processes which mediate ecosystem services. However, riverine ecosystems are currently massively altered by a variety of anthropogenic activities which includes changes in landuse and chemical pollution. LÄS MER

  3. 2. Hydrological control of plant species composition and distribution in Dal River alluvial meadows

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Matouš Jimel; [2023]
    Nyckelord :Riparian zone; Alluvial meadows; Riparian vegetation; Regulated river; Flooding;

    Sammanfattning : Northern boreal alluvial meadows are ecologically significant semi-natural ecosystems within the riparian zone. The effects of disturbance like flooding, grazing, and mowing have historically maintained high nutrient turnover and succession disruption that led to high biodiversity, leading to their inclusion in the Natura 2000 network.

  4. 3. Influence of surface water availability on the distribution of White Rhinoceros in central Greater Kruger

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Julie Mauguiere; [2022]
    Nyckelord :White Rhinoceros; Ceratotherium simum; water provisioning; artificial water; ecological processes; habitat selection; spatial ecology; landscape use; KNP; APNR; SAWC;

    Sammanfattning : The population of white rhinoceros (Ceratotherium simum simum) is now declining in the Kruger National Park (KNP) in South Africa due to the intense poaching crisis ongoing since the early 2000s. The need for an efficient conservation effort has never been greater and requires a better understanding of white rhinoceros distribution in the landscape. LÄS MER

  5. 4. Effects of drought on waterchemistry in a boreal streamnetwork

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Enrique Gómez de Salazar Martínez; [2021]
    Nyckelord :: drought; boreal streams; Krycklan Catchment Study; land cover; biogeochemistry;

    Sammanfattning : Hydrological drought at high latitudes represents a rising environmental hazard induced byglobal climate change. Yet, we still know little about how drought events influence thebiogeochemistry of boreal streams. LÄS MER

  7. 5. Plant functional diversity across a spatial climate gradient in Sweden

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Nina Lončarević; [2019]
    Nyckelord :landscape ecology; plant functional ecology;

    Sammanfattning : Introduction. Climate is a well-known and well-studied abiotic driver of the natural world working through e.g. physiological alterations in species, changes in species’ ranges and growing season, reduction in growth or causing mortality. LÄS MER
